Abstract:
Effective performances particularly on Low-cost housing projects has been a major
problem in many developing countries. In Nigeria, public sector clients have adopted
the design and build (DB) procurement strategy as one of the strategies to deliver Lowcost
housing (LcH) projects following potential benefits to facilitate improved
performances particularly as it pertains to project cost. Yet, many design and build
low-cost housing (DBLcH) projects are not delivered within expected target cost
performances resulting from the influences of waste factors amongst several others
identified. This paper aim to identify the waste factors that significantly influence poor
cost performances of DBLcH projects based on the investigation of the LcH sector in
Imo State Nigeria. A mixed method design, using literature review and survey
questionnaire, was adopted in this study, to identify and validate contextual waste
factors influencing DBLcH project cost performances. Findings revealed the
significant waste factors influencing poor cost performances of DBLcH projects. This
study’s findings is expected to increase the awareness of the project team on the
significant waste factors that will need to be mitigated towards improving the cost
performances of DBLcH projects in Imo State Nigeria.
